Title: Improvements in or relating to Devices for Sorting a Line of Articles into Measured Groups
IPC: B65B23/14
Filed: 1966-05-24
Abstract: 1,152,333. Endless conveyers; batching articles for packaging. SCHWEIZERISCHE INDUSTRIE - GESELLSCHAFT. 24 May, 1966 [26 May, 1965], No. 23004/66. Headings B8A and B8C. A device for sorting into measured groups or columns a stack of flat articles, e.g. biscuits moving on a conveyer 1 comprises means 27 for advancing each successive leading article from the stack on to an incomplete group or column 6a and means for deactivating the conveyer 1 and the article advancing means 27 when a predetermined number or other measurement of articles has been recorded. In one embodiment, the conveyer 1 passing over rollers 2-5 is intermittently driven by a belt 11 passing over a roller (13), (Fig. 3, not shown), coaxial with the rollers 2, the belt being driven by a lever 9 reciprocated to and fro by an eccentric 8. The rollers 2 are connected to the roller (13) by a free wheel coupling which drives the rollers 2 on the forward stroke only of the lever 9. The upright biscuits 6 moving on the conveyer 1 are counted by the engagement of a toothed wheel 20 the movement of which causes, by a pivoted arm, a pair of electric contacts 24 to be closed, which registers the number of biscuits in a control device (47), (Fig. 4, not shown). The biscuits are individually transferred by a compressed air nozzle 27 on to a carriage 16 mounted on the rollers 3, 4 and reciprocated to and fro by a rod 12 connected to the lever 9, the transferred biscuits being pushed against a pivotable stop 17 by a slide 28 actuated by eccentrics 51 and 29. When a predetermined number of biscuits 6a has accumulated on the carriage 16, the air supply to the air nozzles 27 is discontinued by a magnetic valve (48) and the conveyer 1 stopped by a magnetic clutch (49) restraining movement of the lever 9. The slide 28 is moved between the columns 6 and 6a of biscuits by the further rotation of a main drive shaft 7 and the biscuits 6a removed from the carriage 16 by pivotable rubber strips (32), (Fig. 5, not shown) engaging the sides of the stack, the stop 17 being retracted within the carriage 16. The toothed counting wheel 20 may be replaced by a photo-electric cell or by a toggle lever (42), (Fig. 11, not shown) which is pivoted against the pressure of a spring (46) so that a pair of contacts (44) is opened and closed each time the lever (42) engages a biscuit. The biscuits may be divided into columns of a predetermined height, the conveyer 1 being stopped when the column reaches a predetermined length.

Title: Fluid filter apparatus
IPC: B01D29/41
Filed: 1972-05-17
Abstract: 1393708 Automatically back-washing filter S G MOATTI 17 May 1972 [19 May 1971] 23154/72 Heading BID An apparatus for filtering fluids comprises a plurality of filter chambers which are continuously and successively cleaned by backflushing, wherein the back flushing of each chamber is initiated by the rotation of an obturator mounted on a central control rod driven by a fluid-motor which is powered by the pressure of filtered fluid. Figure 1 shows a filter having a lower filter chamber 11 containing a stack of disc-shaped gauze filter elements 1 each of which is divided into eight segment shaped filter chambers 2. Each filter chamber is fed via an inlet 4 from a central annular fluid inlet passageway 6 and delivers filtered fluid outwardly into collection chamber 12 from whence it is returned by outlet 13 to use. A central control rod 10 carries an obturator 7 which rotates within passageway 6 and successively closes the inlets 4 of the chambers 2 of each disc and hence causing backflushing by virtue of the pressure of filtered fluid in chamber 11. The flushing fluid leaves the chambers 2 by conduits 5 and is fed upwardly through the hollow centre of control rod 10 to an upper chamber 8 wherein it is filtered by inward flow through gauze 32 and passed away by conduit 33. The gauze 32 is periodically cleaned by a shock delivered by control rod 10 and springs 36. The control rod 10 is reciprocated by means of a piston 14 to alternate faces of which filtered fluid is successively applied. Obturator 11 is mounted around central rod 10 and has an internally helically grooved surface onto which a catch 16 on the rod engages. Movement of the rod in one vertical direction thus causes rotation of the obturator. A free-wheel mechanism 15 enables the rod itself to rotate on the return stroke so that the obturator is only rotated in one direction. Fluid is applied alternately to opposite sides of piston 14 by means of a reciprocal distributor slide 23 the position of which is changed by the piston 14 reaching each end of its stroke.

Abstract: 857,234. Copying by scanning. CROSFIELD Ltd., J. F. July 17, 1959 [July 18, 1958; Nov. 13, 1958], Nos. 23161/58 and 36563/58. Class 40(3). [Also in Group XL(c)] A colour-component printer for use in an image reproduction process is obtained by exposing a photographic plate 14 in direct contact with the corresponding one of three uncorrected colour separation transparencies 12 in an electrooptical scanner in which light from a cathode-ray tube 6 passes through the transparencies to photo-electric cells 16, the three cell signals being applied to a computer 20 to derive a colourcorrection signal, the signal from the cell representing the colour component corresponding to the printer being applied to a non-linear circuit to obtain a tone-correction signal, and the colour- and tone-correction signals being combined at 19 and applied to modulate the intensity of the scanning spot in the cathode-ray tube. Desirable tone corrections to be effected by circuit 18 are described with reference to Fig. 3 (not shown) and a suitable non-linear circuit is described with reference to Fig. 4, (not shown), (see Group XL(c) ). Plate 14 is provided with a backing filter 32 such that it passes light to which the emulsion is insensitive. Diffusing plates 34 are placed behind the other two transparencies. An additional photo-electric cell responsive to light direct from the screen of the cathode-ray tube may be employed in a system, Fig. 2 (not shown), for removing from the signals from photo-electric cells 16 the modulation imparted by the colour- and tone-correction modulation of the scanning spot. In a modification the modulation signal for the cathode-ray tube may be subtracted directly from the photo-electric cell behind photographic plate 14. The signals applied to the cathode-ray tube may be chopped so that the photo-electric cells produce alternating signals. A rotating drum or oscillating table scanner may be used in place of a cathode-ray tube scanner.
